Forward and reverse chamfering compound tool with drill tip capable of being replaced quickly

Abstract

The invention provides a forward and reverse chamfering compound tool with a drill tip capable of being replaced quickly, and relates to the technical field of machining tools. The forward and reverse chamfering compound tool with the drill tip capable of being replaced quickly comprises a cutter base body and the drill bit, and further comprises a drill bit mounting structure, a forward and reverse chamfering blade and a blade positioning structure, wherein the drill bit mounting structure comprises a threaded connector and a threaded locking hole, the threaded connector is in threaded connection with the threaded locking hole, a vertical sliding hole and a transverse sliding hole are formed in the cutter base body, the forward and reverse chamfering blade is arranged in the vertical sliding hole in a sliding mode, the blade positioning structure comprises a limiting ejector rod, an elastic telescopic piece, an abutting column and an adjusting bolt, the limiting ejector rod, the elastic telescopic piece and the abutting column are sequentially located in the transverse sliding hole, one end of the limiting ejector rod is in limiting clamping connection with the forward and reverse chamfering blade, the adjusting bolt is installed in the transverse sliding hole in a threaded mode, and the adjusting bolt abuts against the abutting column. According to the forward and reverse chamfering compound tool with the drill tip capable of being replaced quickly, the drill bit capable of being replaced quickly and the forward and reverse chamfering blade capable of being replaced quickly are adopted, so that the manufacturing and machining cost is greatly reduced, and the manufacturing cost is reduced while high-quality and high-efficiency machining is guaranteed.

Description

technical field [0001] The invention relates to the technical field of machining tools, in particular to a quick-change drill point front and back chamfering compound tool. Background technique [0002] Hole machining is one of the most commonly used methods of material removal, accounting for 20-40% of the total machining process, depending on the industry. On the flexible tool processing center, the drilling process accounts for about 30-35% of the total processing time. Hole processing plays an important role in the aviation manufacturing industry. Tens of millions of holes are processed every year on an aircraft assembly line, so hole processing tools account for a high proportion of processing costs. In the hole processing tool, the integral carbide drill can be used. The quality and accuracy of the hole processed by the carbide drill are high, and the processing efficiency is also high. Poor and easy to break, the cost of the solid carbide drill bit is too high, whic...

Problems solved by technology

In the hole processing tool, the integral carbide drill can be used. The quality and accuracy of the hole processed by the carbide drill are high, and the processing efficiency is also high. Poor, easy to break, resulting in too high cost of solid carbide drills, which greatly affects the application range in the field of hole processing, and it is difficult to apply in a large scale in the market

In addition, in the hole machining that requires positive and negative chamfering, most of the existing technologies still require two-knife and two-sequence machining methods to realize entrance chamfering and exit chamfering respectively. The operation is cumbersome and affects work efficiency.
